Description EGroupware is a web-based groupware server written in PHP. A SQL Injection issue exists in the core components of EGroupware, specifically in the Nextmatch filter processing. Authenticated attackers can inject arbitrary SQL commands into the WHERE clause of database queries. This is possible due to a PHP type juggling issue where JSON decoding converts numeric strings into integers, bypassing the is int() security check. The vulnerable component is the Nextmatch filter.
